According to industry online statistics, in August, the production of rotary compressors was 10.412 million units, a year-on-year increase of 24.29% and a decrease of 19.9% ​​from the previous period; sales of 10.066 million units, a year-on-year increase of 19.59% and a decrease of 15.8% from the previous quarter. In the fiscal year from January to August, the cumulative output was 106.5 million units, a year-on-year increase of 25.34%; the sales volume was 107.142 million units, an increase of 23.91% over the same period of last year.
In the past 14 years, sales activities have become more apparent, and air-conditioning companies have maintained a relatively high level of procurement for rotary compressors, achieving a full-year increase from January to August, and accumulated sales for the first eight months have exceeded 100 million units.
In the future, the growth rate of domestic sales to products will gradually decline, and exports will show signs of recovery in some markets, such as Latin America.
Duplex Stainless Steel Tubes / Pipes, are made by Duplex stainless steels, can be both seamless and welded tubes.
Depending on different steel grade and diameter, and wall thickness of the Duplex Stainless Steel Tubes.
Duplex stainless steels are called [duplex" because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel.
The result is a microstructure of roughly 50% austenite and 50% ferrite.
Duplex stainless steels have a two-phase microstructure of austenite and ferrite grains.
The main differences in composition, when compared with an austenitic stainless steel is that the duplex steels have a higher chromium content, 20–28%; higher molybdenum, up to 5%; lower nickel, up to 9% and 0.05–0.50% nitrogen.
